Application filed January 12, 192B. Serial No. 612,175.

My invention relates to machines for building the carcasses of cordtires, and particularly to machines designed for carrying out themethods set forth in my Patents Nos. 1,422,046 granted VJuly L1, 1922,and

1,423,929 granted July 25, 1922. and constructing tires according to myPatent No. 1,401,148 granted December 27, 1921, reissued July 11, 1922as No. 15,405.

l0 Among the objects of my'invention l may mention the building of tirecarcasses in greatly reduced time; `the more accurate positioning of thecords of the tire carcass; the building of a tirecarcasswith the cordsunder uniform and balanced tensions; the .improvement of mechanism forapplyingthe bead reinforcements; and the improvement of the constructionof the carcasses in various other ways which will appear from thefollowing description and claims. Other objects will appear from thepatents above referred to.

Before describing the machine in detail, reference may be made to themanner of its operation. Avcircumferential series ofseparate cords orstrands is directed in converging relation from a source or sources ofsupply such as a creel used in warp-handling machinery. These cords areindividually 3o guided by movable guides which carry them down the sidesof the tire-building support or core. The core is mounted so as to havea motion along its axis, wh-ereby it is passed from one side to theother of the series of guides, and also a motion of rotation about itsaxis, whereby the cords are laid diagonally upon the core. lVhile thecore is at the side of the guides, and the guides in their inwardpositions holding th-e cords down the side of the core, a bead applyingmechanism closes about the series of-cords and winds bead materialcircumferentially in place. Upon the retraction of the bead mechanism toits inactive position the core and .guides resume their motio'ns, thecoaction being such that the cords are maintained under tension at alltimes. The combined result of all these devices is to lay the cordmaterial diagonally back and forth across the core in a plurality ofreverse folds, progressing outwardly through successive plies, andhaving an annular bead anchorage enclosed Within each reverse fold.Various other devices used in connection with those mentioned above willbe described below.

The invention will now be describedy in connection with theaccompanyingdrawings, in which- Y Fig. 1 is a side elevation of a machinev Fig. 5kis a detail of the same gearing,`
